[SJDXA] Steppir Urban For Sale

[Ross Lambert]

I have decided to sell my brand new 90 % constructed Steppir Urban antenna
with controller.

I bought it new last year at Dayton and have assembled all of the
electronics, motors and boom. It's been tested and working perfectly.
I have decided to go with a bigger Steppir which is the only reason for
selling .
The long elements have been assembled and all that remains is the
completion of the curved sections and final assembly.
I also have the optional watertight  junction box. The transceiver
interface cable, 125 feet of controller cable and some other options.
Have all manuals

I have over $2300 invested in this antenna. Will sell for $1700 firm, pick
up only

“Putting up a conventional aluminum beam can present challenges for some
homeowners due to size and aesthetics. With a 4-foot boom length and
turning radius of under 16 feet, but still covering 40 through 6 meters,
the UrbanBeam solves a lot of problems for the urban or suburban ham trying
to get an effective HF signal. At under 45 pounds, it’s easy to turn, and
easy to mount on a pole or roof. ”

“It’s a great 20m-6m Yagi, and on 30m and 40m provides performance close to
a dipole, but in a smaller space. Because it’s a SteppIR, it’s elements are
tunable to your operating frequency, which radiates as much of your signal
as possible.

Because it doesn’t look like a conventional antenna, it can be deployed in
‘difficult’ situations. I’ve been using this antenna to work DX from my
suburban neighborhood for the last seven years, and no neighbor has even
asked what it was. This antenna is too good not to share.”

“When Mike first told me about the UrbanBeam, I said ‘send me the first
one’” enthuses Martti Lane, OH2BH, DXer extraordinaire and Ham Radio
Raconteur.

“Small can be beautiful as DX operators want to travel compact and light –
yet producing enough signal on each major band to reach every household the
world over! Our recent EA8BH pending regional win in the ARRL DX SSB
Contest was accomplished with a SteppIR. To win, you need to be loud!”
